The LaserFlow® Ex velocity sensor remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and noncontact Ultrasonic Level technology. The sensor uses these advanced methods to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream. The sensor can be installed in hazardous areas defined as Class 1, Div 1, Zone 0.The sensor uses an ultrasonic level sensor to measure the level and determines a sub-surface point to measure velocity. The sensor then focuses its laser beam at this point and measures the frequency shift
of the returned light. The LaserFlow Ex is ideal for a broad range of wastewater monitoring applications. With Teledyne ISCO’s TIENet™ Barrier, it is compatible with both the Teledyne ISCO Signature® Flowmeter and the 2160 LaserFlow Module, depending on the type of installation. With its specially designed mounting bracket in place, the LaserFlow Ex
can be deployed and removed from street level. This avoids the risk and expense of confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about data quality can
be recorded and transmitted with the flow data. Additionally, built-in diagnostic tools simplify installation, maintenance,and advanced communication options reduce site visits.
